I ordered mine on Jan 28th and production began on Feb 2nd. CA tells me it is scheduled to be completed around Feb 10th and she expects it to be here ( in DC) by the beginning of March.
I think the timeline took longer for earlier orders because production and shipping was geared toward initial dealer stock. Also, production efficiency was expected to increase (raising daily build numbers) near the end of the 1st quarter. Orders now to the east coast should be to the dealership between 30-45 days at this point.
